50 THE CANADIAN ENTOMOLOGIST 



name was an oversight, even if timbra was to be retained. The 

 genitalia of exprimens and cilisca differ, which supports my 

 view as to their being two species. The treatment of stilla 

 is new. I have only one specimen, from Dr. Barnes, and had 

 suspected that it might quite possibly be a variety of expri- 

 mens, and have seen Vancouver Island specimens of the lat- 

 ter coming very near stilla. 



Ipimorpha Hbn. I believe that suhvexa (2726) is very likely a 

 variety of pleonectiisa (2724). I long ago suggested that 

 nanaimo (2725) might be subvexa, but the authors keep the 

 three distinct. I possess nothing named nanaimo, and am 

 content to accept it as it stands for the present. 



Enargia Hbn. Injumata Grt., with punctirena as a synonym, is 

 listed as a form of decolor Walk. This is in accordance with 

 Hampson. Had I not seen the two in nature side by side, 

 and found one sometimes present in certain seasons without 

 the other, I should probably have held the same opinion, 

 and the male genitalia being alike would lend support to that 

 view. As it is, I hold to my former opinion that they are 

 two very closely allied species. 



Eutricopis Morr. Elahorata Hy. Edw. is a form with the dark 

 markings rather thickly irrorate with yellow scales. The 

 placing of the name by the authors as a synonym of nexilis 

 Morr. seems to indicate that the latter is of this form also. If 

 that is so, then the much darker form with purplish or vinous 

 red shades, found at a high altitude in the Rockies, deserves a 

 varietal name. 



Catocala heaniana Grt. This stands as a form of nnijuga. The 

 form was unknown to me until quite recently when I 

 examined the type. It is very difficult for me to believe that 

 the reference is correct. Dr. McDunnough has doubtless seen 

 it, and confirmed Hulst's reference, which was followed by 

 Smith. 



Ccenurgia Walk. Sohria Walk, appears, as in Hampson, as a 

 synonym of crassitisciila. Grote referred it to erechtea, and
